Abstract (en)
Provided is a method for producing fluorine gas, capable of suppressing clogging of pipes and valves with mist. Fluorine gas is produced by a method including electrolyzing an electrolyte in an electrolytic cell, measuring an intensity of sound generated near an anode in an inside of the electrolytic cell as the electrolyte is electrolyzed in the electrolyzing, and sending a fluid generated in the inside of the electrolytic cell in the electrolyzing the electrolyte, from the inside to the outside of the electrolytic cell through a flow path. In the sending, the flow path in which the fluid flows is switched in accordance with the intensity of sound measured in the measuring an intensity of sound, such that the fluid is sent to a first flow path that sends the fluid from the inside of the electrolytic cell to a first outside when the intensity of sound measured in the measuring an intensity of sound is not more than a predetermined reference value, or the fluid is sent to a second flow path that sends the fluid from the inside of the electrolytic cell to a second outside when the intensity of sound measured in the measuring an intensity of sound is more than the predetermined reference value. The predetermined reference value is 10 dB or more and 60 dB or less.
